SoK: An Overview of PPG's Application in Authentication [article]

Lin Li, Chao Chen, Lei Pan, Jun Zhang, Yang Xiang
<span title="2022-01-27">2022</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
In particular, Photoplethysmography (PPG) measures the change of blood flow of the human body by an optical method.  ...  The unique advantages (simple acquisition, difficult to steal, and live detection) of the PPG signal allow it to improve the security and usability of the authentication in various aspects.  ...  Another non-contact method of detecting heartbeat signals is based on the Ultra-wideband radar.  ...
